As a molecule of water, explain your journey through a plant from the moment of entry in the root to your involvement in photosynthesis.

Water enters a plant through the root hair along the concentration gradient. From the roots cells water moves into the xylem. Xylem is the major water conducting tissue in the plants. The main driver of water movement in the xylem is the transpiration. Transpiration is the loss of water from the aerial parts of plant. in this way water moves up to the leaves where water is used in the photosynthesis.
